Greptile Summary

This PR swaps the bottom-left console promo banner from the relationships-out-of-beta announcement to a new Presences API announcement, updating the image asset, title, message, and CTA link accordingly.

• bottomAlerts.ts: replaces the old promo entry with a new presencesApiPromo object pointing to the new image and blog URL.
• presences-api.png / relationships-out-of-beta.png: new promo image added; old one removed.

Confidence Score: 4/5

The change is minimal and well-contained, but the CTA URL slug should be confirmed before merging to avoid a broken link in production.

The PR description cites announcing-presence-api (singular) as the target blog URL, while the code uses announcing-presences-api (plural). If the published post uses the singular slug, the "Read announcement" button will lead to a 404 for all users who click it. Everything else in the change is straightforward.

Important Files Changed

src/lib/images/promos/presences-api.png	New promo image asset for the Presences API announcement banner.

URL slug mismatch with PR description

The PR description states the target blog URL is https://appwrite.io/blog/post/announcing-presence-api (singular "presence"), but the code uses https://appwrite.io/blog/post/announcing-presences-api (plural "presences"). If the published blog post slug uses the singular form, every user who clicks "Read announcement" will hit a 404. Please verify the exact slug against the live or staged blog post before merging.
